A 1-year-old infant with asplenia syndrome and congenital heart disease consisting of common atrium, common inlet left ventricle with a common atrio-ventricular (AV) valve, pulmonary atresia, and total anomalous pulmonary venous connection was admitted to our hospital for radiofrequency catheter ablation (RFCA) of supraventricular tachycardia (SVT) before total cavo-pulmonary connection. After antiarrhythmic medications were discontinued for RFCA, she suffered from SVT that resulted in the rapid deterioration of hemodynamic status. Antiarrhythmic medications and cardioversion were not effective in terminating SVT. The baseline electrocardiogram confirmed the existence of twin AV nodes; however, this SVT was revealed to be focal atrial tachycardia (AT) with enhanced automaticity. The origin of AT was not related to surgical scar. Emergent RFCA for AT was successful in our case of asplenia syndrome. AT is a life-threatening complication in a single ventricle and delayed treatment can be fatal. It is important to perform RFCA promptly when drug treatment is not effective. We suggest that the AV node is not always the target site for ablation in patients with asplenia syndrome and twin AV nodes. <Learning objective: In the case of supraventricular tachycardia with asplenia and twin atrio-ventricular (AV) nodes, atrial tachycardia (AT) as well as AV reentrant tachycardia could occur. AT is a life-threatening complication in infants with single ventricle. If drug therapy is not effective, emergent catheter ablation should be performed. AV node is not always the target site for ablation in patients with asplenia and twin AV nodes.>.

BACKGROUND Heterotaxy is a syndrome of abnormal arrangement of the internal thoracic-abdominal structures across the left-right axis of the body. It is a primary disorder with 2 main settings - bilateral left sidedness (polysplenia syndrome) or right sidedness (asplenia syndrome) - although some overlapping or uncertainties may occur. Patients with right heterotaxy typically present with asplenia, complex heart disease, and other thoracoabdominal organ situs abnormalities. CASE REPORT We present a unique case of congenital asplenia syndrome with complex heart disease, annular pancreas, and other extra-heterotaxic anomalies (e.g., musculoskeletal) in the form of a radius aplasia and partial syndactyly of the thumb and index finger of the left hand. These associated anomalies have not been reported before. CONCLUSIONS This case shows the need for paying increased attention to the implications of other extracardiac anomalies that can be associated with heterotaxy syndrome.
